ARTlFICIAL-STONE BLOCK.

SPECIFICATION forrhing part of Letters Patent No. 782,351, dated February 14, 1995. Application filed September 10, 1903. SerialNo. 172.545.

T0 all whom it 7nay concern:

Be it known that I, MARCELLUS Q. MUL- LENIX,a citizen of the United States, 'residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Artificial-Stone Blocks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in artificial-stone blocks, and more. particlarly to such artificial blocks composed of cernent, concrete, or other suitable composition which are used as a facing or veneer for the walls of buildings, prefrably of wood.

The invention is in a general way an improvement upon the construction set forth in United States Letters Patent Nos. 598, 624 and 627 ,960, granted February8, 1898, and J une 27, 1899, respectively, t0 John Brower,and has for its object to provide a simpler and less expensive but equally efficient structure of a character such that the cernent block may be attached directly to the wall, the backingplate or back piece set forth in said Letters Patent being dispensed with.

To these ends the invention consists in certain novel features, which I will now proceed to describe andwill then particularly point out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of a portion of a structure embodying my invention, the same being shown in an incomplete or partly-cofistructed condition. Fig. 2 is a vertial sectional view tl1 rough one of the blocks and detached. Fig. 3 is an end view of one of the corner-blocks, the same being shown in position on the wall.

In carrying out my invention I employ blocks oomposed wholly of cernent or other suitable composition, and I embed in said blocks fastening strips securely anchored therein and having their projecting portions lying in the plane of the back of the block, so that when the block is applied to the wall its back will lie directly against the same and the anchoring strip or strips will also lie fiat against the wall, so as to be adapted for direct attachment thereto by mails, screws, or other suitable fastenings.

Referring to the accompanying drawings,

1 indicates the walls to be faced or veneered,

said walls being shown as composed in the present instance of uprights or posts 2, although it. is obvious that said walls may be provided with the usual external sheathing. The ordinary blocks of the wall-courses are indicated at 3 and are constructed in the usual form rectangular in cross-section and having a fiat rear face 4. Within each block there is embedded during the process of molding or otherwise constructing the same one or more fiat fasteningstrips 5 of sheet metal, such as iron and also preferably galvanized or otherwise provided with a protective coating. The portion of the strip 5 which is wholly embedded in the block and which is indicated by the reference-numeral 6 is preferably located centrally therein or midway between its front and rear faces, its location being in any event sufiiciently far enough from the back of the stone to preVent its breaking out. The inner end of the strip, which is usually its lower end, is provided with an anchoring device to prevent the strip from pulling ont longitudinally this object'being accomplished by bending the extremity of the strip at an angle to the main embedded portion thereof, as indicated at 7. The outer end of the strip, which is usually its upper end, is first carried back from the point where it emerges from the body of the block to the rear face thereof, as indicated at 8. This portion of the strip issunk into the face of the edge of the block, so that its upper surface lies flush with the surface of said edge. The

remaining portion of the strip, Which may for the wall, thus doing away with any back plate or supportingpiece of any kind interposed between the wall and the blocks. The sheet metal of which the strips are composed is of a thinness such as to not materially interfere with the bearing of the remaining blocks against the wall. By this means the cost of construction is materially reduced and the construction materially simplified without in any way impairing the efiiciency of the structure.

The corner-blocks are preferably provided with'a round or extension 1l, arranged at right angles to the body of the blocks, so as to extend around the corner alternately from opposite directions in the manner indicated in Fig. 1. The bodies of these corner-blocks are indicated by the numeral 12.

I do not wish to be understood as limiting myself strictly to the precise details of construction hereinbefre described and shown in the accompanying drawings, as the same may obviously be modified withoutdeparting from the principle of my invention.

Hving thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

An artificial built block of cement or other suitable composition, comprising a composition body having a substantially fiat back, and a fiat fasteningstrip of thin sheet metal embedded in said body in a plane forward of the back of the block in a vertical position, said strip being anchored in said body by having its inclosed terminal portion bent at an angle, said strip extending rearward from the point where it issues from the block to the rear of the blOck, said rearward-extending portion being flush with the adjacent surface of the edge of the block, and said strip having a projecting portion extending outward from the block with its rear surface in the plane of the back of the block, substantially as described.

In testimony whereof I aifix my signature in presence of tWo witnesses.
